Title:
POWER SUPPLY SYSTEM AND METHOD FOR OPERATING POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/187305
Kind Code:
A1
Abstract:
A power supply system (1) is provided with: a distribution board (2) that has a circuit (L1) to which single-phase three-wire system alternating current power is supplied from a power system (10); a fuel cell device (3) that outputs single-phase three-wire system alternating current power; a storage cell device (4) that outputs single-phase two-wire system alternating current power; and a transformer (5) that is provided between the fuel cell device (3) and the storage cell device (4), and converts the single-phase three-wire system alternating current power and the single-phase two-wire system alternating current power to each other. The circuit (L1) includes a voltage wire (u) and a neutral wire (o) to which an essential load (22) is connected, the storage cell device (4) supplies the single-phase two-wire system alternating current power to the voltage wire (u) and the neutral wire (o) and supplies the single-phase three-wire system alternating current power to the fuel cell device (3) via the transformer (5) during a power failure of the power system (10), and the fuel cell device (3) supplies the single-phase two-wire system alternating current power to the voltage wire (u) and the neutral wire (o) via the transformer (5) during the power failure of the power system (10).
